Paramecium caudatum
Biological Process
organelle assembly
Cellular Component
trichocyst
Developing trichocyst containing a paracrystalline core surrounded by amorphous material and an autophagosome containing mitochodrion. TEM taken on 1/25/74 by R. Allen with Hitachi HU11A operating at ...

Cross section through the more anterior part of the oral region showing the four more loosely spaced rows of cilia making up the quadrulus and more compact cilia of the peniculi on the left hand wall ...
CIL:39158
NCBI Organism Classification
Paramecium caudatum
Biological Process
oral apparatus organization
Cellular Component
oral apparatus
Cross section of the oral region (buccal cavity) posterior to the vestibulum. The cytopharynx is beginning on the dorsal surface and the ribbed wall, peniculi and quadrulus are present on the right an...

NCBI Organism Classification
uncultured scuticociliate
Biological Process
cilium axoneme assembly
Cellular Component
cilium axoneme
A view of the locomotor ciliature of Conchophthirus. This includes the nature of the cell membrane and axoneme. The negative magnification is 22,000X. The raw film was scanned with an Epson Perfection...
CIL:39251
NCBI Organism Classification
Didinium nasutum
Biological Process
ciliary cell motility
Cellular Component
oral apparatus
Didinium nasutum showing the two prominent girdles of cilia in full metachronous beat. If you look at higher magnification you will see the occasional short, blunt clavate cilia. These are known to no...
CIL:39311
NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
plasma membrane organization
Cellular Component
pellicle
This view shows a transverse ridge cut with its sloping side lying tangentially in the section plane. The granulo-fibrillar filled peaks are prominent. Striated bands appear sectioned closer to their ...

Paramecium multimicronucleatum
Biological Process
plasma membrane organization
Cellular Component
pellicle
Freeze fracture image of the surface ridges at the anterior end of the cell where kineties to the right and left sides come together at an angle at the anterior suture tip. In this area are numerous p...
CIL:39314
NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
plasma membrane organization
Cellular Component
plasma membrane
In quick-freeze deep-etch preparations the plasma membrane can be seen to contain plaques or plates of intramembrane particles (IMPs) that are regularly aligned in rows with a center-to-center spacing...
CIL:39316
NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
plasma membrane organization
Cellular Component
plasma membrane
A row of large IMPs bordering parts of the plates are visible. Two parentheses-shaped empty trichocyst docking sites are also present and one ring surrounding pits where the rosette IMPs have been rem...

NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
cortical cytoskeleton organization
Cellular Component
cell cortex
The infraciliary lattice in this quick-freeze deep-etched image consists of a meshwork of branching fibers composed of many subfibers. Basal bodies and trichocyst tips extend through the openings of t...
